When she chooses a man, it's worthy to be king. It is a frequent theme of Irish mythological texts, as in the famous wooing of Etain '(Tochmarc tin), where Tin is Ireland itself, and is the object of rivalry between the kings and the gods, until, in the later version, it is converted to Christianity. Medb is also (and especially) in the great epic called Tain Bo Cualnge ( 'La Razzia des vaches de Cooley'), whose hero is the main sublime warrior Cuchulainn. Queen Medb, to prove to her husband Ailill it is so rich that he decides to buy the best bull of Ireland, brown Cualnge, located in the northern province, Ulster. But Ulate (inhabitants of Ulster) are unwilling to sell him, and she decides to conquer by force. But let's not count on Cuchulainn, who alone shall determine the armies of the four-fifths of Ireland in bloody fighting singular. Medb appears in other stories, and even in modern Irish folklore, but this is more a sort of queen of ghosts, in a setting in Ireland no Roman Christianity, where the ancient gods and heroes are often assimilated to demons or evil creatures.
